Ring For Jeeves could be considered PG Wodehouse's deconstruction of his own stories. The usual romantic comedy character-relation tropes are there, but the world they live in is remarkably different. All of Wodehouse's stories take place in a Genteel Interbellum Setting, but Ring For Jeeves explores what would happen if time actually progressed. World War II has happened, Britain is in the throes of social upheaval which separates Jeeves and Bertie (Bertie is sent to a school that teaches the aristocracy how to fend for themselves), poverty and suicide and graphic death are acknowledged, and Jeeves even admits to having "dabbled in" World War I. The book's setting, Rowchester Abbey, is falling apart at the seams and the characters who inhabit it start to feel like a pocket of old-fashioned happiness in a darkening world. In case any doubters still exist about 3/4 through the book, there's Constable Wyvyrn's musings about just how much the world has changed.
And then there's Greaves, This is Serious, by William Mingin, another Wodehouse deconstruction. Bertie begins to grow dissatisfied with his carefree life of idle frivolities, and begins questioning his butler Greaves to see if they ever do anything... productive. The answer is quite chilling.
